The free map to start with
Begin with the MassGIS Interactive Property Map; it covers every tax parcel around Arlington and Belmont. For property near Malden, put in a street address, an owner's name or a parcel number, and the matching parcel lights up. For acreage around Everett, the parcel card normally shows the owner of record, acreage on the tax roll, a parcel ID and often a sale date.
Somerville, MA: the basics
Somerville lies within Middlesex County, Massachusetts, and the county assessor maps its lots. If you're looking near Medford, the municipality handles things like zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Lots just outside the city limits out by Everett generally answers to county rules instead.
Neighboring parcel maps
Middlesex County borders Essex County, Norfolk County, Suffolk County, Worcester County, and Hillsborough County, NH, and each of those keeps its own parcel map.

Near Cambridge, the Platbookmapper state page links every neighboring county map across Massachusetts.
Before you lean on the lines
